## About This Module

The Core module is the main entry point into the NVIDIA<sup>&reg;</sup> DriveWorks SDK.
It provides features that most applications use, such as
context handles, system/platform information, and memory management.

In the case of context handles, this module creates and releases
SDK context handles. The following information is stored in those handles:
- All global components, such as a pointer to the logging callback.
- NvMedia device instance.
- Global timesource.
- Platform information.
- Virtual file system.

Each individual module must have a handle to a valid context instance.

When a module is created within a certain context, its availablility and
functionality exists only in that context.
